Staying true to its peripheral nature, Mophie's outed yet another iPhone companion: the Juice Pack PRO. Although the new power-boosting case doesn't carry as much juice as that Powerstation (not surprising, really), it does offer similar ruggedized aesthetics -- which should come in handy the next time you decide to take your Cupertino handset on a hazardous trip. Mophie notes the Juice Pack PRO can more than double the iPhone 4 / 4S life with its 2,500mAh battery, but the company's also placing a hefty amount of focus on the add-on's water splash, sand, impact and shock protection features -- these, naturally, earned the PRO a MIL-STD 810G (Military Standard) rating on the testing grounds. If all that makes this Juice the one for you, then gather up $130 and head over to the Mophie site to snag one for yourself.
